ROLLER-BEARING.

Patented Nov. 1918.

Original afiplication filed July 27, 1916, Serial No. 111,588. Divided and this application filed November 21,

a 1917. Serial No. 203,160.

To all whom it may concern:

Be it known that I, BENGT Wm'roR FJELLMAN, subject of the King of Sweden, residing at Gottenborg, in the Kingdom of Sweden, have invented certain new and use-' ful Improvements in Roller-Bearings, of which the following is a specification.

This invention relates to double row roller bearings having outwardly tapering conical rollers, and a spacing device between the rows of rollers located in position relatively to the transverse central plane of the bearing to receive the thrust from the race frings which tends to move the rollers inoi the hearing. The object of the'invention wardly toward the transverse central plane is to provide a spacing device which will present the minimum friction to the rollers while engaging them in the most effective region. The improvement provides a spacing device having engaging the rollers in the region of their axes, a further object of the invention being to provide a combined spacing device and cage for the balls, and in. certain embodiments of the invention the cage for the spacing balls forming a retainer both for the rollers and the balls.

This present application is a division of my copending application SerialNo. 111,588'

led July 27, 1916, for roller bearings, the drawings in this application constituting Figure 10 of the drawings of said parent application as originally filed. I

In the drawings accompanying this application a. racticable embodiment of my invention is i ustrated in which drawings Fig. 1 is a longitudinal section of one-half or the bearing;

Fig. 2 is an elevation of se ent of the cage shown in Fig. 1, it being roken away at one of theball seats;

Fig. 3 is a detail ofthe cage-in longitudinal section at about the plane of line'3-3,

ig. 4 is a view of the portion of the cage shownin Fig. 2, looking at this from the the left-hand side;

Fig. 5 is a, longitudinal section ofone-hal f of the bearing, showing a modified form of cage; and p Fig. 6 is a view similar. to Fig. 2 and showing the cage of Fig. 5.

The inner ring l of the bearing is shown in Figs. 1 to 4 provided with a spherical of balls 13.

a plurality 'of .balls for jacent wlngs 6, which wings wardlv taperin race,'and th'e outer ring 2 is shown provided with two conical races having their apices on the axis-of the bearing. Between the rings there are mounted two sets of rollers 4 which are also shown conical in shape, the apices of the-cones coinciding with the apices"of the cones formed by the outer races. rollers for spacing the same apart is a series The ends of the rollers at the Placed between the two rows of point of engagement with the balls are accuratel ground so that the rollers will be proper y positioned by the balls. The spacing device maintains the .rollers proper positions relatively to the radial center plane of the the\ thrust of the rollers to move inwardly of the illustration, the balls are a ring 5 having suitable seats for the balls and constituting a cage therefor.- The ring 5 is shown provided at both sides with wings or projections 6 designed to enter between the rollers of each set or row and keep the rollers at each set at predetermined distances from one another. Each roller is shown located in the space between two ad-- position the rollers' in respect to the balls and the ball in their tendency seats. The ring 5 will thus be seen to constitute a retainer or spacer for the rollersland a cage or retainer for theballs to posiion each in respect of the other.

The balls 13 are shown placed in pockets in the form of holes in the ring 5. In Figs. 5 and 6 the balls 13 are shown disposed in outwardly open pocketsin theirin in which latter case they are preferalfiy kept in osition by an outer ring 14'.

hanges may be made within the scope of the claims without departing from the spirit of the invention. v

I claim as my invention 1. A double row. roller bearing having outwardly tapering conical rollers, the inner the proximity of the axis of each.

2. A double row roller bearing having outconical rollers, the inner end of each roller eing provided with an accurately ground face at the region of its axis, a

in their 1 bearlngs and recelvesv bearing. In the shown carried by p magma spacing ring located between the rows of rollers and provided with a series of ball pockets, and balls in the said pockets and engaging the said accurately ground faces on the inner ends of the rollers. v

3. A double row roller bearing having outwardly tapering conical rollers, the inner end of each roller being provided with an accurately ground face at the region of its axis, a spacing ring located between the rows of rollers and provided at both sides with wings or projections located between the rollers, said ring also having pockets ad- 'jacent the spaces between the Wings for receiving balls, and a ball in each of said pockets.

4. A double row roller bearing having outwardly tapering conical rollers, the inner end of each roller being provided with an accurately ground face at the region of its axis, a spacing ring located between the rows of rollers and provided at each side with wings adapted to enter between the rollers, the spaces between the said wings on the respective sides of the spacing ring being in alineinent axially of the bearing, and said ring having pockets at such spaces for receiving balls, and a ball in each such pocket located in position to engage the innor end of a roller of each row.

In testimony whereof I affix my si nature.
